Created attachment 7652 Screencap of Settings Editor Hello all, I normally have just one panel. I wanted to test the practicality of having the workspace switcher on a separate panel, and created a new panel with the switcher. I didn't like it, so I moved the switcher back to panel 1, and wanted to remove panel 2. I could not find any (working) way to do this. Each time I remove the panel using the '-' in the panel dialog, it disappears, end reappears. At the moment panel 2 disappears, panel 1 also briefly disappears, then both reappear again. Using the Settings-editor, I can't seen to find a way to remove panel 2 either (attached screenshot of panel 2 data).
On a terminal, run: xfce4-panel -q xfce4-panel Now try to remove the second panel, check if any error message is given.

By your description of the panels disappearance, it's very likely that it crashes when you try to remove the second panel, but nothing suspicious is to be found from the terminal output you provided. It reminds me of bug #14144, since we're talking about the workspace plugin, but that bug is for the gtk3 version of xfce4-panel. Unfortunately I can't reproduce this bug with neither 4.13 nor 4.12 versions.
Maybe useful experiences: - By accident, I clicked on the '+' butt and added a new panel. Now I cannot close that panel either. - I tried to remove the panel switcher from Panel 1, but xfce4-panel crashed and I had to restart it from a terminal - As there was no easy way to hide the extra panels, I went looking for the configuration file, (and found it at ~/.config/xfce4/xfconf/xfce-perchannel-xml). Indeed, there were 3 panels defined, so I removed the sections for Panel 2 and 3. On restart, they re-appeared. I noticed a strange definition at the 'panels' section of the xml: <value type="int" value="1"/> <value type="int" value="2"/> <value type="int" value="3"/> So, I suspected this were the panel IDs (though they have other names assigned), and deleted 2 and 3 (and re-deleted panel 2 and 3). After a restart, I'm back to 1 panel - hurray. Re-added the workspace switcher, and I'm back to normal (for now)
